on a new project with bars/beats:
-make a new track
-import an audio region
-turn off snap
-move region to the right a little so it is no longer 'snapped' to a bar line
-turn snap to beats
-press the left region trim handle and move it to the left
-the region moves to the left as if it was in the red outlined 'move region' mode.

of course this only happens on regions where the trim handle is fully extended to the left.

not a biggie, but when making small adjustments on these type of regions you can think your moving a trim handle when in fact you've actually moved the entire region.
